Abstract: Direct photolysis of 1-(ortho-(methoxymethyl)phenyl)-1-phenylsilacyclobutane yields three isomeric products attributed to intramolecular trapping of an initially formed silicon-carbon biradical intermediate by migration of the benzylic methoxy group to silicon, along with the (expected) intramolecularly ether-stabilized silene due to formal [2+2]-cycloreversion.
